The opening ceremony for this year’s Olympic Games proved to be an impressive success overall – but U.S. music fans were upset by certain musical performances being cut from the NBC telecast, and they made sure to make their disappointment known.

Several sets were supplanted by advertisements during the recent broadcast of the 2012 opening ceremony, which took place in London, England. The Arctic Monkeys delivered a show-stopping rendition of the Beatles’ ‘Come Together’ that did make the telecast; however, the segment featuring their own hit ‘I Bet You Look Good on the Dancefloor’ was replaced by an ad break.

Additionally, punk legends the Sex Pistols’ performance of their well-known song ‘Pretty Vacant’ and Emeli Sandé’s delivery of the spiritual hymn ‘Abide With Me’ – which was sung in commemoration of the lives lost in the devastating terrorist attack in London back in 2005 – were not included in the broadcast. English singer-songwriter Frank Turner was also left out of the televised program.

As has become quite common these days, people used social media to voice their heated opinions on the matter. According to a recent report, disgruntled U.S. viewers made their feelings known on Twitter, punctuating their complaints with the hashtag "#nbcsucks."
